Title: Method and equipment for evaluating compound semiconductor field-effect transistor circuit
Inventor: YANO HITOSHI
IPC: H01L21/66
Filed: 1992-05-14
Abstract: PURPOSE:To extract imperfect transistors in a circuit which are caused by the side gate effect, by detecting light emission from the periphery of a transistor part which light has energy larger than the forbidden band energy of a semiinsulative substrate, in the state that a field-effect transistor circuit is operated by DC or AC. CONSTITUTION:Electrons generated on the interface between a channel 6 of a first FET and a semiinsulative substrate 8 flow into the channel 6, and absorbed by a positive potential drain electrode 3. Positive holes are made to flow toward a side gate by a side gate electrode 4. Excessive positive holes are stored on a diffusion barrier wall between an N<+> region 9 under the side gate electrode 4 and the semiinsulative substrate 8. The positive holes recombine with electrons flowing from the N<+> region 9, via recombination centers. A part of the positive holes radiates light as the result of transition across the forbidden bandwidth, so that the light emission from the side gate electrode periphery is detected by using an equipment capable of detecting photons whose energy is larger than the band gap, and an imperfect state can be extracted.

Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To speedily and surely manage the passing of an objective body such as a person trying to pass through a gate by previously sending identification information to the side of an identification means from the signal originating means of a testee approaching to a prescribed distance. SOLUTION: When the testee enters a prescribed distance, an antenna 41 receives the identification information signal PS of the signal originating means 10 held by he testee. A receiving means 40 sends identification information IPS to the collating data base 101 of the identification means 100. A data base 101 sends a finger print collation data group corresponding to identification information IPS to a collation data extraction array part 103. When the testee places his finger on he collation input means 90, fingerprint collation data of the testee is sent to a collation part 102, which compares this fingerprint collation data with he fingerprint collation data group stored in the array part 103. When coincident data is included, the collation part 102 sends an operation signal OS to an actuator 69 to open a gate board 68.
